Part of the Yanmar Parts Manuals.
All 169 pages of this Yanmar Crawler Backhoe Parts Catalog (OEM #Y00K2471) are organized around one job: putting the right part number in your hand for the B37-P, B37-PR, B37-C, and B37-CR. You get exploded-view diagrams covering every assembly from the control valve and turning motor to the driving motor, boom cylinders, and bucket attachments. Inside: a full hydraulic oil piping section with connector, flange, and O-ring part numbers; cab and canopy electrical harness breakdowns; and a dedicated crawler assembly with link, pin, shoe, and master components listed by OEM number. The B37-P and B37-C travel at 4.1 km/hr high and 2.1 km/hr low; ground pressure on your pad is 0.246 kg/cm². Stop hunting part numbers across forum threads. Bookmarked by system, searchable by keyword; open it on your tablet, pull the number, and order the part.
